Abstract: This paper improves the identification algorithm given in[1] for raw material blending process. The improved algorithm is very suitable for the time varying process and can track the time varying parameter with high accuracy in time. Actual computation examples are provided. Compared with the results of algorithm[1], the new algorithm has a higher identification accuracy, more rapid convergence.

Key words: material blending, method of calculation, computer simulation
